WebJan 19, 2024 · At Asiacrypt 2024, coded-BKW with sieving, an algorithm combining the Blum-Kalai-Wasserman algorithm (BKW) with lattice sieving techniques, was proposed. … WebWe provide several applications of these algorithms, improving the best known quantum algorithms for subset sums, the BKW algorithm, multiple-ecryption and the approximate k-list problem. Outline. In Section 2, we recall some preliminaries of quantum computing, state the di erent problems that we will solve and recall previous results. Section 3
WebWe provide the first time-memory trade-offs for the BKW algorithm. For instance, we show how to solve LPN in dimension k in time and memory . Using the Dissection technique due to Dinur et al. (Crypto ’12) and a novel, slight generalization thereof, we obtain fine-grained trade-offs for any available (subexponential) memory while the running ... WebThe BKW algorithm consists of two phases, the reduction phase and the solving phase. In this work, we study the performance of distinguishers used in the solving phase. We show that the Fast...
Web(BKW) algorithm [9] for LWE with discrete Gaussian noise. The BKW algorithm is known to have (time and space) complexity 2O(n) when applied to LWE instances with a prime modulus polynomial in n[29]; in this paper we provide both the leading constant of the exponent in 2O(n) and concrete costs of BKW when applied to Search- and Decision-LWE. WebJul 29, 2024 · Optimized implementation modified the BKW algorithm reported at [7] demonstrates how the efficient computation required for breaking LPN problems are memory-bounded, and it required about 15...
WebA comprehensive analysis of the existing LPN solving algorithms, both for the general case and for the sparse secret scenario, shows that for a sparse secret there is another algorithm that outperforms BKW and its variants.
